But the MK-I Halo puts you in full control over which temperature to use. with temperature settings ranging from 140°F to 450°F. This range is ideal for all hair types, including fine and dry, and are also compatible with keratin treated hair and chemically straightened hair.

Eventually, you have to do a bit of experiment on your own to find the perfect temperature setting for your hair. This is because the ideal temperature would differ between individual and it is something that is determined by many factors and one of them is the thickness, dryness and curls of your hair.

Nonetheless, it gives you a peace of mind to know that you can adjust the temperature up to the maximum of 450°F, which is required by ladies with thicker and curlier hairs.

Dual-floating Ceramic Plates

Upon use, I could immediately tell that the Onei MK-I Halo ceramic flat iron was a high quality product. This is because instead of using single floating plate as in other low-priced models like Conair Infiniti, Onei MK-I Halo Ceramic flat iron boasts dual floating ceramic plates.

The good does not stop there. The plates have been coated multiple times, making it durable enough to hold up to frequent use. This feature is mostly seen in expensive salon exclusive equipment, so it is exciting to see it in a consumer product that is in the medium price range.

Infrared Technology to Reduce Hair Damage

The infrared technology utilized in this particular model produces less damage on the hair, making it the perfect choice for anyone who is worried about breakage or dryness.

In addition to this, the MK-I Halo also has an elliptical barrel which allows you to not only straighten, but curl and flip your hair as well. I was impressed by this feature, but found that the one inch edge was difficult to work with for long hair types.

The Onei MK-I Halo comes with a standard 30-minute automatic shut off safety feature and an ultra bright display, allowing for easy temperature readings and adjustments.

However, the temperature adjustment chimes are located very close to the display and may be prone to accidental adjustment. This is a common concern in many hair straightener reviews.

Overall, I believe that the Onei MK-I Halo ceramic flat iron is an excellent choice if you want salon quality results and want to minimize the damage to your hair.

Weighing the Pros and Cons

The Case for Buying It

The Onei MK-I Halo has multi-coated ceramic plates that are typically found in higher end models in the likes of Paul Mitchell Pro Tools and usually cost much more.

It also has an incredible four year warranty, which is rarely found in consumer-level hair straighteners. Compare this to Croc Flat Iron which offers a rather pathetic 90-days warranty and Rusk Flat Iron which offers a 1-year coverage.

A swivel cord makes this straightener feel more like a salon straightener as well. This model also has a full range of temperature settings which puts you in full control over the heat and you can determine the idea temperature for your hair conditions.

This particular feature is one of my favorites and is a core component of hair straightener reviews. Most similarly priced models lack this key feature.

What You Need to Keep in Mind

I did not like the temperature adjustment and panel layout on the front and feel like it could lead to accidental changes in temperature.

While the elliptical barrel is an excellent feature, the one inch edge may not be suitable for long hair. But aside from these, I think Onei MK-I Halo Ceramic flat iron might just be the best flat iron you can get for the price tag it fetches.

The Bottomline

Overall, I found that the Onei MK-I Halo ceramic flat iron is made of durable materials and has a beautiful modern look.

It has many exciting features that are rarely seen in consumer-level straighteners, making it the perfect hair straightener choice for anyone seeking to get salon quality results from the comfort of their own home.
